I want to try the AMD platform for a desktop system, I can search the web and come up with a combo but it may not be readily available @ Lam Rd.
Please suggest a combo that can be readily sourced in Mumbai.
ASUS M4A785D-M PRO. Warning needs kernel >2.6.3x and X >= the one in Ubuntu 9.10.
Thanks for the mobo ref. but what about CPU? Also, have you tried Linux KVM in this setup?
For example on the Intel systems that I have, the mobo BIOS have "Virtualization" Enabled/Disabled option. In disabled mode the kvm modules do not load. In enabled mode the kernel automatically loads the KVM modules, create the /dev/kvm device and the KVM guest OS work like a charm. After the guest OS "settles" down, the host OS cpu/RAM utlization is hardly noticeable. Response time within the guest OS is quite good running on 128MB to 512MB RAM (runlevel 3).
Whereas on my Acer 5542 laptop (4GB RAM - 256MB for video), the BIOS does *not* have any "Virtualization" flag. However, the AMD Athlon II X2 cpu (not the Turion version) does support KVM. I can load the KVM modules manually. I can start KVM guest OSs but the performance of the KVM guest OS is very sloooow and the CPU utilization goes upto 80% or more and stays there - the motherboard and CPU combo are not optimized for KVM IMO. (I am using the same VMs from the Intel systems for comparison purpose)
With my experience with the Acer , I am a bit hesitant to plop money and then find out, the system is a lemon with respect to Linux KVM.
Me using it as a home multimedia box. simultaneous D1 encode/decode.
I would appreciate if you could share your LKVM performance (if any).
Thanks. -- Arun Khan
